Adjustable and constant voltage supplies, for temperature rise testing
Description
REO high-current power supplies are used wherever test objects with several thousand amperes need to be tested. In particular, these are switching devices, fuses, cables, etc. The test specimens are thermally heated and tested under nominal conditions in endurance tests. Tests are also carried out with defined overload curves. Traditional voltage adjustments with variable transformers ensure that the input signal is passed through to the output as a clean sine wave. This means that every test with test specimens can be tested with any current value and sinusoidally and reproduced at any time. the high-current sources are controlled electronically and can achieve a control accuracy of (< 0.5 % and can be integrated into the laboratory network via various BUS systems)
Advantages
- Single- or three-phase high-current supplies
- AC supplies up to 30 kA
- The modular construction of the different units (variable unit, control unit, power section)
Typical applications
Temperature rise tests of components such as cables and contacts, low voltage distribution, switchgear with
low impedances.
